Tunnel crack identification, prediction and distribution characteristic test simulation verification method and system

The invention provides a tunnel crack identification, prediction and distribution characteristic test simulation verification method and system, and relates to the technical field of tunnel crack test verification models, and the method comprises the steps: obtaining tunnel face crack distribution data in an actual tunnel, simulating the overall tunnel crack distribution, and constructing a tunnel solid model; a tunnel excavation process is simulated, and the three-dimensional shape of each tunnel face and the distribution of various fractures are constructed according to the intersection relation between the fracture distribution of the whole tunnel and each tunnel face; according to the actual tunnel drilling position, setting model drilling hole distribution, and simulating and visualizing the intersection process of the drilling hole and each crack; according to each constructed model, acquiring three-dimensional information and color information of each tunnel face, and obtaining effective data for crack
